Participants

Reaction Steps

The amine from Example 8A (34 mg, 0.1 mmol) was dissolved in THF (0.5 mL) and Et3N (15 mg, 0.1 mmol) and ethyl chloroformate (13 mg, 0.12 mmol) were added at 0° C. after which the mixture was allowed to stir overnight. HPLC purification gave the titled compound (10 mg, 24%). 1H NMR (300 MHz, DMSO-D6) δ 9.14 (s, 1H), 7.32 (d, J=8.7 Hz, 2H), 7.08 (m, 4H), 7.08 (s, 1H), 6.61 (d, J=9.0 Hz, 2H), 3.96 (m, 2H), 3.28 (q, J=6.6 Hz, 4H), 3.02 (d, J=16.5 Hz, 1H), 2.73 (m, 2H), 2.36 (m, 1H), 2.05 (m, 1H), 1.13 (t, J=6.9 Hz, 3H), and 1.05 (t, J=7.2 Hz, 6H). (one proton (ArCHnHbC(C═O)) overlapped with water)). MS (ESI) positive ion 410 (M+H)+; negative ion 408 (M−H)−.
